Published in 2025 at "Mathematical Methods in the Applied Sciences"

DOI: 10.1002/mma.70140

Abstract: We consider the nonlinear elliptic system u∈W01,q(Ω):−div(M(x)∇u)+u=−div(uM(x)∇ψ)+f(x),ψ∈W01,2(Ω):−div(M(x)∇ψ)=Φ(u),$$ {\displaystyle \begin{array}{ll}u\in {W}_0^{1,q}\left(\Omega \right):& -\operatorname{div}\left(M(x)\nabla u\right)+u=-\operatorname{div}\left(u\kern0.3em M(x)\kern0.3em \nabla \psi \right)+f(x),\\ {}\psi \in {W}_0^{1,2}\left(\Omega \right):& -\operatorname{div}\left(M(x)\nabla \psi \right)=\Phi (u),\end{array}} $$ where Ω$$ \Omega $$ is a bounded, open subset… read more here.

Published in 2025 at "International Journal for Numerical Methods in Engineering"

DOI: 10.1002/nme.7629

Abstract: The Stokes equations are used to model the motion of fluid flows where inertial terms can be neglected. Traditional finite element approaches such as the Taylor–Hood element do not ensure local conservation pointwise of the… read more here.

Published in 2019 at "Computer Methods in Applied Mechanics and Engineering"

DOI: 10.1016/j.cma.2018.12.013

Abstract: Abstract For meshes of nondegenerate, convex quadrilaterals, we present a family of stable mixed finite element spaces for the mixed formulation of planar linear elasticity. The problem is posed in terms of the stress tensor,… read more here.

Published in 2021 at "Frontiers in Endocrinology"

DOI: 10.3389/fendo.2021.629100

Abstract: Thyroid hormone (TH) plays important roles in the developing brain. TH deficiency in early life leads to severe developmental impairment in the hippocampus. However, the mechanisms of TH action in the developing hippocampus are still… read more here.

Published in 2021 at "Frontiers in Immunology"

DOI: 10.3389/fimmu.2021.663041

Abstract: Despite the enormous morbidity attributed to schistosomiasis, there is still no vaccine to combat the disease for the hundreds of millions of infected people. The anthelmintic drug, praziquantel, is the mainstay treatment option, although its… read more here.
